“…The investigators hypothesized that more intense fetal movements while riding in a car, in which sitting posture is standard, are a direct result of more exposure to vertical vibratory accelerations (transmitted through the seat and backrest) within the range of resonance frequencies of vital organs in the abdominal cavity (Kromka-Szydek et al, 2018). A study by Irannejad Parizi et al looked at the forces applied to the gravid uterus and fetus (in head-down, occipito-anterior position) while riding in a passenger vehicle and experiencing sudden acceleration by passing over a speed-bump (Irannejad Parizi et al, 2021). Using their model, they recommend that a driver should not hit a standard speed-bump (0.5 m wide and 0.12 m tall) at 42 km/h or faster in order to avoid risk of fetal head injury.…”

In numerous medical conditions, including pregnancy, gravity and posture interact to impact physiology and pathophysiology. Recent investigations, for example, pertaining to maternal sleeping posture during the third trimester and possible impact on fetal growth and stillbirth risk highlight the importance and potential clinical implications of the subject. In this review, we provide an extensive discussion of the impact of maternal posture on fetal physiology from conception to the postpartum period in human pregnancy. We conducted a systematic literature search of the MEDLINE database and identified 242 studies from 1991 through 2021, inclusive, that met our inclusion criteria. Herein, we provide a synthesis of the resulting literature. In the first section of the review, we group the results by the impact of maternal posture at rest on the cervix, uterus, placenta, umbilical cord, amniotic fluid, and fetus. In the second section of the review, we address the impact on fetal-related outcomes of maternal posture during various maternal activities (e.g., sleep, work, exercise), medical procedures (e.g., fertility, imaging, surgery), and labor and birth. We present the published literature, highlight gaps and discrepancies, and suggest future research opportunities and clinical practice changes. In sum, we anticipate that this review will shed light on the impact of maternal posture on fetal physiology in a manner that lends utility to researchers and clinicians who are working to improve maternal, fetal, and child health.

“…While a commercial airliner pulls about 0.2-0.4G’s in the horizontal direction during take-off, electric vehicles, such as Tesla’s Model S, can pull upwards of 1.15G’s horizontally, which may have relevance in pregnancy. Equally intriguing is the speed-bump paradox – a long-used traffic safety measure in speed-calming zones, the speed-bump, due to the sudden acceleration it exerts on the vehicle’s occupants, has been recently investigated and posited as a potential public health risk in pregnancy ( Irannejad Parizi et al, 2021 ). We hope this review spurs future research directions and has relevance to development of guidelines for posture in various activities encountered in pregnancy from preconception to postpartum.…”

There are several well-known medical conditions in which posture and gravity interact with natural history, including pregnancy. In this review, we provide a comprehensive overview of interactions between maternal posture and maternal physiology and pathophysiology at rest during pregnancy. We conducted a systematic literature search of the MEDLINE database and identified 644 studies from 1991 through 2021, inclusive, that met our inclusion criteria. We present a narrative review of the resulting literature and highlight discrepancies, research gaps, and potential clinical implications. We organize the results by organ system and, commencing with the neurological system, proceed in our synthesis generally in the craniocaudal direction, concluding with the skin. The circulatory system warranted our greatest and closest consideration–literature concerning the dynamic interplay between physiology (heart rate, stroke volume, cardiac output, blood pressure, and systemic vascular resistance), pathophysiology (e.g., hypertension in pregnancy), and postural changes provide an intricate and fascinating example of the importance of the subject of this review. Other organ systems discussed include respiratory, renal, genitourinary, gastrointestinal, abdominal, and endocrine. In addition to summarizing the existing literature on maternal posture-physiology interactions, we also point out gaps and opportunities for further research and clinical developments in this area. Overall, our review provides both insight into and relevance of maternal posture-physiology interactions vis à vis healthcare’s mission to improve health and wellness during pregnancy and beyond.
